-I would like to open a Multipage PDF with settings set to open "all pages" and "import pages as links".
If the pdf has only one page import it also as a link (if possible do it)

• Import an Illustrator *.ai file Multi-layouts by importing them as links across multiple layouts.

• Set flattener presets:

• preset name

• various parameters...

• Select all (Select / All)

• Run the command: Object / convert transparency / Previously saved preset / OK

• I saw among the commands that there is an openOptionsFreeHand could I create a script that opens the freehand files for me?

How could I do? some things I found but others not.
I can't find a manual that explains how to use the various script commands and options. All very technical and not very intuitive and detailed. An infinite list of commands but then how to use them is not understood.
